' v8 Claims.

This invention relates to journal boxes for railway cars, particularly that type that have'what are-known as free oiling systems of lubrication.

One object of our invention is to provide means prise a removable baille positioned between the oil conveying member and the inner end of the journal box. i

. Another object of our invention is the provision of means to limit movement of the journal box away from` the vjournal after the parts have'been. assembled to prevent displacement of and damagetocertain of theparts. This means is preferably combined or associated 'with the removable baffle, Other objects and advantages of our invention kwill be apparentfrom the following detailed description taken vin conjunction with the drawings, in which:

Figure 6 is a partial sectional view' taken'on line 6--6 of Fig. 5, and

Figure 'l is a partial sectional view'illustrating the method of assembly of the baille.

Referring to the drawings, lthere is showny a journal yI extending into the journal box 2. The journal box may be'enlargedy at its forward end, providinga deepened portion to forman oil reservoir 3. The usual ybrass 4' and wedge 5 are positioned between the top of the journal, vand the 45' under surface 5 of the top of the journal box.

Secured to the end of the journal, as bybolts l, is a paddlemernber or clipper 8 arranged to rotate with the journal and convey oil to the top of the box. The clipper may beformed with dissimilar'fend portions 9' and I0 that are adapted to extend downwardly into the oil reservoir, and during the course of its rotation at low speeds to drop oil into a trough Il in a projecting portion l2'of thevwedge. At high speeds the oil adhering to the dipper's thrown by centrifugal force onto the upper wall I3 of the journal box and runs down into troughs I4, I4 and from there dropsv into the trough Il. The oil is then conveyed by the usual passages I5 in the brass to the bearh ing surfaces on the journal. that necessary to properly lubricate the journal drops to the bottom of the box and normally nds its way back into the oil reservoir 3. The usual dust guard i6 and obturating ring Il may be used to prevent dust from entering and oil escaping from the box. The front end of the journal box may be closed by the cover 'i8 and made oil-tight by the use of gasket I9. Stud bolts 2li and nuts 2! are used to secure the cover tothe box.

We have found that, if means are not provided to prevent it, the action of the clipper striking the oil is apt to deflect small particles thereof from the reservoir rearwardly in such a manner that it strikes the under side of the journal and is again dellected toward the rear of the box into such a position that it may escape through the bottom of the dust guard slot 22 or otherwise find its way out of the rear of the journal box.

Since this type of box is designed to run for comparatively long periods without the further addition of' oil, it is obvious that even small quantities of oil escaping from time to time through therear of the box will soon deplete the initial oil supply `to a dangerously low point. In order to prevent this escape of oil, we provide a novel baille member 23 comprising a substantially vertical portion 24, vformed at its upper end with a substantially horizontal web l25, from which web extends another Vertical portion 26. Extending rearwardly from the web 2li is an axially projecting portion 21 which, as will be clearly seen from Figs. 1 and 5, is offset vertically from the web 25 for a `purpose to be later described. The baille may be reinforced along its side and bottom yedges by a flange 28. The baille member is positioned within the journal box behind projections 29, 29 located on either side of the box. An upstanding web 3l] in thebottom of the reservoir may be provided in front of the baille to hold the bottom thereof against forward movement. Extending rearwardly from the member 23 are substantially horizontal supporting brack-r ets 3l which are adapted to rest on the bottom wall 32 of the journal box. These brackets may be reinforced by vertically extending webs 33, 33.

In order to function according to one of the objects of this invention, as will be later more fully described, the baille must be applied after the journal box has been assembled with its brass The excess oil over.

and wedge over the journal. Accordingly, we have provided novel means for maintaining the baille in position without sacrificing ease of assembly and disassembly. For this purpose we use a iiat member 34, preferably made of spring steel, extending across the front face of the baille and into overlapping relation with the projections 29, 29. The spring member is drawn tight against the baille and projections by means of a bolt 35 and a nut 36. Since access to that portion of the box rearwardly of the baille is impossible when the latterr is in position, we provide a recess 3l (see Figs. 4 and Gladapted to receive the head of the bolt and prevent it from turning.

Lugs 38, 38 are adapted to be bent over the head in the manner indicated in Fig. 4, after the lat ter has been assembled with the balile to hold the bolt in position. 'Ihese lugs may be originally formed, as illustrated by the dotted lines in Fig. 4, to permit insertion of the head of the bolt into the recess. The spring member 34 should be prevented from turning after it has been assembled as by means of lugs 39, 39 extending for.

wardly from the member 23.

In order to limit upward movement of the baiile, we provide lugs 40, 4B on the front side thereof which enter notched portions 4| 4| of the projections 29, 29. Openings 42, 42 are formed in the baille member to permit return of the oil to the forward portion of the oil reservoir.

It will be understood that the brass 4 and the wedge 5 are inserted after the journal box has been jacked up relative to the journal. Considerable damage may be done to the dipper if the box is thoughtlessly raised when the dipper is in vertical position, as shown in Figs. l and 2, due to the fact that heretofore means has not been provided to limit relative vertical movement between the journal box and the journal. It will be appreciated that without some means to limit upward movement thereof, the journal box may be raised to such an extent that the dipper will contact the lower wall of the box, causing the dipper to be bent out of shape. Furthermore, in assembling the trucks to which the journal boxes are applied and also under certain conditions encountered in service the journal brass and wedge may move out of their normal positions and cause a hot box if permitted to run without correcting the displacement. To obviate these difficulties, we have provided means on the baille member 23 to definitely limit upward movement` of the box and maintain the brass and wedge in operative position. It will be noted that the bale is constructed with the vertical portion 26 offset rearwardly from the main portion 24. This offset will allow for suicient axial movement of the journal relative to the box without the collar 43 of the journal contacting the'portion 26 of the bailie. The portion 21 is spaced a smalldistance beneath the journal and obviously forms a stop which will limit upward movement of the box relative to the journal so long as the baille is in operative position. The clearance between portion 21 and the journal is preferably small enough to insure maintenance of the proper relation between the brass and wedge. The upper surface 44 of the web 27 may be made concentric with the journal, as will be seen from Fig. 2.

In Fig. 5 we have illustrated the adaptability of the member 23 to diierent sizes of journals. In service, journals of various diameters may be encountered for a given capacity journal due to wear or because they have been turned down shim and the under side of the journal may be c the desired amount. In Fig. 5 the dot-dash line represents the normal diameter of thejournal,

whereas the solid line illustrates a journal having a diameter slightly smaller than normal. It will be noted that the clearance between the surface 44 and the dot-dash line is substantially the same as the clearance between surface 46 and the solid line. This, of course, is merely illustrative, and theclearance lbetween the baille member and the journal may be made any desred amount that will limit upward vmovement.

of the journal box to such an extent as will positivelyv prevent damage to the dipper yand retain the parts in place.

In assembling, the combined baille and stop member is iirst entered in a substantially horizontal position, as shown by the solid lines in Fig. 7, so that its widest portion passes through the notches 4|, 4I in the projections 29, 29. It is then rotated to a position as shown by the dotdash line and further moved to a verticalposition behind the projections 29, 29 and 30 and seated therea'gainst. The spring member 34 and nut 35 are then applied to lock the baille rigid with the box.- It will be noted that the member 23 is cut away at the bottom'at 41, 41 to form a portion of slightly less width than the distance between projections 29, 29; so that as further rotation is prevented by the upper portions of the extensions 29, 29, the lower part of the baille 4| but may move between the projections 29, 29:l

I-Iowever, the member can be used in journal boxes in which there is ample clearance for it to be inserted, even `though it is vof the same widthv throughout its vertical extent. I To avoid damage to the journal and as a convenience in assembling, member 23 may be beveled as at 48 and 49 so as to provide suiiicient clearance between these surfaces and the corner 50 and the like of the box.

It will be noted that the baille member is positioned intermediate the ends of the enlarged portion 3 of the oil reservoir, thus dividing it into a pair of compartments. Any dirt entering the box through the dust guard will collect in the space between the rear side of the baille and the rear wall of the portion 3 up to the level of the bottoms of openings 42. In this manner foreign matter is prevented' from passing into lthe forwardpart of the reservoir where it could be carried by the dipper to the-bearing surfaces.

While we have shown our invention applied to a construction having a typical free oiling mechfV anism for journal boxes, itis apparent that it may be used with journal boxes of various kinds.
